Abstract: Abstract New .alpha.-chlorinated carbonates, their method of manufacture and application in the protection of the amine functions of amino acids The invention relates to new .alpha.-chlorinated carbonates charac-terized in that their formula is:                      in which  X  is a fluorine, chlorine or bromine atom and  R1 is different from the     group and represents:     - a substituted or non-substituted,saturated or unsaturated, aliphatic, araliphatic, primary, secondary, tertiary or cyclo-aliphatic radical.            These .alpha.-chlorinated carbonates are prepared by the action of a compound of formula  R1OH  on a chloroformate of formula:       in a solvent medium in the presence of an acid scavenger which is added after the two preceding compounds.            They are used to block the amine function of amino acids.  The .alpha.-chlorinated carbonate and amino acid are reacted in a solvent medium at a temperature of -5° to 100°C in the presence of an acid scavenger.  Blocked amines are very useful in peptide synthesis.

Abstract: ABSTRACT OF DISCLOSURE         The specification discloses an improved row cleaning apparatus to be mounted on a tractor-drawn planter unit to clean away mulch and crop residue without cultivation of the soil.  The cleaning action of the present invention improves depth control and planting speed of  the planter unit  and  facilitates  seed germination while retaining the mulch and residue between crop rows for erosion control and yield enhancement.  The row cleaner disclosed herein comprises a pair of toothed wheels journaled for rotation about  intersecting axes mounted on the planter unit ahead of the furrow opener.  The toothed wheels are mounted with their teeth intermeshed above  the soil surface and rotate  in planes symetrically inclined downwardly, outwardly, and forwardly of the direction of travel of the planter unit.   The toothed wheels penetrate the soil ahead of the furrow opener to a depth sufficient for the forward motion of the planter unit to drive the wheels in rotation, thereby clearing mulch and drop residue from  the  path  of  the  planter  unit,  yet  not  so  deep  as  to substantially cultivate the soil.  The advancing planter unit is thus presented with substantially bare, untilled soil.

Abstract: Abstract A connector for assembling two structural members.            A connector (15) for assembling two furniture parts such as a tabletop and an associated table leg. The connector (15) comprises a screw (1) provided with a head (2) and a relatively long shaft (3), and a bushing (4) with outer holding means (45) and a through hole (6). The bushing (4) is pivotally mounted on a smooth part (7) of the shaft (3) and is axially fixed as one terminal surface (8) thereof abuts the head (2) of the screw (1) and the opposite terminal surface (9) thereof optionally abuts a locking means (30) projecting from the shaft (3). One of the terminal surfaces of the bushing (4) comprises a contact knob (11) delimiting the turning of the bushing (4) relative to the screw (1) to an angle less than 350° when it abuts a stop projection (10) projecting from the screw (1). When a table leg and a tabletop are to be assembled the bushing (4) is initially turned into a hole in the table leg by means of a mounting tool. Subsequently the screw (1) is screwed into the tabletop by turning the table leg about its longitudinal axis until it abuts the tabletop and the desired tightening force has been achieved. Then the table leg can be turned backwards an angle less than 350° until the desired positioning of the table leg relative to the tabletop has been obtained and without chang-ing the tightening force therebetween. As a result a table leg of a cross section corresponding to a triangle can always be secured to a rectangular tabletop and adjusted into its correct position where the right angle of the triangle opposes the right angle of the corner of the tabletop without thereby changing the achieved tightening force be-tween the tabletop and the table leg.

Con-necting structure is provided establishing a limited loss motion connection between the shafts and includes control structure to release one pair of the brake shoes responsive to torque input to the input shaft above a predeter-mined minimum in the first direction and to release the other pair of brake shoes responsive to an equal amount of torque input to the input shaft in the opposite direction.  Further, brake release structure is provided for shifting all of the brake shoes toward release positions thereof only when torque loading on the output shaft in either direction is below a predeter-mined low value.

Abstract: A B S T R A C T     A printed web marker is used in combination with a multiroll printing press.  A web marker is positioned downstream of the last of the rolls for marking defective portions of the printed web.  A central controller operates the marker and the controller has off, delay and on control modes.  The marker does not operate when in the off mods and marking commences upon expiration of a predetermined period when the controller is shifted from the off to the delay mode and continues thereafter and for a predetermined period after the controller is shifted from the delay to the off mode.  Marking commences instantaneously upon the controller being shifted from the off to the on mode.  Switches and operators cause the controller to be shifted between the modes so that only defective portions of the web are marked.

Abstract: ABSTRACT    A system for the control of a member for following a moving object, especially a small object being part of larger entity, comprising an ultrasonic transmitter and receiver is characterized in that each sensor unit is fixed to the means of movement of a follower member. The ultrasonic sensor units are inexpensive and relatively insensitive to the dirt prevalent in an industrial or an agricultural environment. Since the sensor units can be brought relatively close to the object to be followed, the influence of the distracting larger entity is reduced and an accurate control system is obtained using simple reflection-sensing of the object. The control system can be applied in a milking apparatus. Furthermore the invention provides a method for the automatic milking of an animal.
